絮凝-微电解法处理雷尼镍废水的工程应用

Engineering application of flocculation-microelectrolysis to the treatment of Re-Ni-containing wastewater

初步探索用絮凝 -微电解法处理含重金属离子———镍废水的可行性。工程以雷尼镍废水为处理对象 ,确定用絮凝 -微电解法处理含Ni和Ni2 + 废水 ,并通过调节pH和沉降 ,使工艺排水总镍质量浓度≤ 1.0mg/L ,对废水的COD的去除效果达 2 0 %～ 4 0 %。

Preliminary exploration of the feasibility to treat the wastewater containing nickel ion(heavy metal ion) with flocculation-microelectrolysis method. The process is to treat Ni/Ni 2+ containing wastewater (named Re nickel wastewater) ,and to decrease the total Ni concentration in the drainage process ≤1.0 mg/L by adjusting pH value and sedimentation. The effect of COD removal reaches to 20%～40%.
